Background : Chrysanthemum indicum L. is used in medicine, for bee, ornamental as multivoltinism plant resources. The purpose of this study was to evaluate methods of rooting promotion to make high quality medicinal plants, thereby increasing farm income. This study investigated the effects of different cuttage period, extraction site, shading degree, nursery tray for promoting cutting slips rooting in Chrysanthemum indicum L. Methods and Results : It is used New variety "Gamkuk 1" that were forstered in Gyeongsangnam-do Agricultural Research & Extension Services. Method of application with cuttage period were conducted under five condition; Around the middle of April, Toward the end of April, Early in May, Around the middle of May, Toward the end of May. Early in May plant length was longer than other cuttage period as 41.2%, 83.7% and are significant at significance level 0.05. Method of application with extraction site were conducted under three condition; 1 - 3 node, 4 - 6 node, 7 - 9 node. Leaf number in 1 - 3 node was more than other extration site as 19.4%, 33.6%. Also root length in 1 - 3 was more than other extration site as 10.5%, 23.2%. Method of application with shading degree were conducted under three condition; 50%, 70%, 90%. Plant length in 50 - 70% was longer than 90% shading degree as 23.8%, 24.2%. Also shading degree 50 - 70% had many root length and root number. Method of application with nursery tray were conducted under five condition; 72, 105, 128, 162, 200 tray. Plant length in 105, 128 tray was longer as 8.5 - 35.3% than other nursery tray and are significant at significance level 0.05. Conclusion : According to the results, Early in May, extraction site 1 - 3 node, shading degree 50 - 70%, nusery tray 105, 128 showed the highest growth on cutting slips root promotion in Chrysanthemum indicum L.
